Answer to Question #69581 in Physical Chemistry for MEJ

Question

One mol of an ideal gas with initial volume of 1m3 at 50K & 2bar undergoes a four steps mechanically reversible cycle in a closed system?

In step 1-2 the volume is increasing to 5m3 at a constant pressure of 2bar; in step 2-3, pressure decreases at constant volume to 1 bar and a temp of 100 K in step 3-4 the pressure increases to 10 bar by an isothermal process; and in step 4-1 the gas return by constant volume process to initial state. * Calculate Q, W, ∆U, and ∆H for each step of the cycle. Take Cv =3/2 R; CP=5/2 R
